Returning from the original is Dick Van Dyke as Mr Dawes Jr, though we do hope he has worked on the accent - he's had the best part of 50 years to do so, after all.

He said of returning: "I'll be going to London in the spring to do my role, and I get to do a little song and dance number. I gotta be a part of it."

The sequel is set in 1930s London, and will follow a grown-up Michael and Jane, alongside his three children and housekeeper. However, when Michael suffers a personal loss, the flying nanny re-enters his life to bring joy.
